The clinical trial approval for the mRNA herpes zoster vaccine has been recently received from the U.S. Food and Drug Administration (“FDA”). This is the second innovative vaccine product of the Group approved by the U.S. FDA for clinical trials, following the mRNA RSV vaccine, which marks a new milestone in the Group’s globalization strategy.

In preclinical testing, results from a third-party testing unit showed that the Group’s mRNA herpes zoster vaccine specific T-cell immunity, specific IgG antibody titers, and fluorescent antibody to membrane antigen (FAMA) titers were significantly higher than those of international commercially available recombinant subunit control vaccines.
